signor to Ford Motor Company, Dearborn, Mich, a corporation of Delaware Filed Jan. 6, 1959, Ser. No. 785,255 Claims priority, application Great Britain Early 17, 1953 2 Claims. (Cl. 268-129) This invention relates to window regulators for motor vehicles.

The invent-ion consists of a window regulator for motor vehicle windows of the kind comprising a glass sheet slidable in a support channel comprising a rotatable drum and a cable or cables therearound extending upwards and downwards of the support channel from the drum and respectively secured to the window adjacent the top and bottom parts thereof, whereby rotation of the drum in one direction lifts the window and in the other direction lowers it.

Conveniently the drum is rotated over a locking clutch to provide against slip, and has a suitably arranged balance spring.

The cable conveniently passes within the side support channel between it and a glazing channel secured to the glass edge, the lower portion passing through a recess between the side support channel and the lower plastic bearing attached to the glazing channel. This shields the cable against water.

This regulator operates on one plane to avoid any wear on the cable.

Conveniently also the drum is mounted in a bracket secured to the outside of the support channel, the thickness of bracket and drum not greatly exceeding that of the channel whereby the assembly can be readily lowered into the interior of the door.

This assembly method eliminates the necessity of large holes in the door inner panel usually necessary with a conventional door regulator, thereby reducing the incidence of water and dust leaks into the passenger compartment of the body.

The regulator can readily be designed to be suitable for right or left hand doors without change. The door regulator operating handle is passed through the door inner panel and clipped or fastened by equivalent means, through to the regulator body. To avoid handed assemblies it is possible for the regulator handle to be inserted into the regulator body from either side dependent on the door assembly employed.

The invention will be further described with reference to the accompanying drawings.

FIGURE 1 is a perspective view of an arrangement according to the invention.

FIGURE 2 is a perspective view of a further embodiment of the invention.

In the drawing of FIGURE 1 the glass sheet 1 is provided with a glazing channel 2 secured along one side and a bottom glazing channel 3 along the bottom. Side and bottom glazing channels 2 and 3 are joined by a gusset 4.

Glazing channel 2 is attached to two bearings 6 of plastic bearing material such as nylon or polytetrafiuoroethylene which slide within the side support channel 5.

To the outside of support channel is secured the drum 7 within a supporting bracket 8, and round the drum is a cable 9 extending at one end upwardly to a hook 10 secured adjacent the top of the window glazing channel 2 and at the other end downwardly round bearing 6 and the gusset 4, and up to a tensioning block 12 in which fits the threaded sleeve 13 at the end of the cable with the securing nut 14 thereon. Any other convenient method of tensioning could be used.

The drum 7 is driven by an internal flat spiral spring 15 which is engaged at its inner end through an antireverse clutch with hub 16. The shank of handle 17 can be inserted into a matching orifice in hub 16 from either side of the drum 7.

When applied to a rear door the complete assembly can be as for the front door but with the addition of a remote operation to locate the regulator handle to a convenient location. This remote drive can be housed in an applied garnish moulding.

One means is shown in FIGURE 2 where the handle 17 drives a drum 18 mounted forwardly of the rear door 19 which over a cable 20 drives the drum 7 which operates as in the description of FIGURE 1.

It will be understood that the invention is not to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope of the invention, as defined in the appended claims.

What is claimed is:

1. In a vehicle body having a window opening and a window well therebeneath, access to said window well being through a longitudinally extending slot, a support channel extending from within said well upwardly into said window opening, a glass panel slidable in said support channel at one side thereof, bracket means attached to said support channel at the opposite side thereof, said glass panel and bracket being in alignment in a horizontal direction lengthwise of the glass panel with the longitudinal axis of said slot, the width of said slot being greater than the width of said support channel and bracket to provide for insertion of the latter into said window well through said slot, rotatable drive means including a cable receiving drum carried by said bracket, cable means around said drum extending upwardly and downwardly from the drum relative to said support channel, said cable means being respectively secured to the glass panel adjacent the top and bottom parts thereof, and means operable to rotate said drum in one direction or the other to raise or lower said glass panel.

2. In a vehicle body having a window opening and a window well therebeneath, access to said window well being through a longitudinally extending slot, a support channel extending from within said well upwardly into said window opening, a glass panel slidable in said support channel at one side thereof, bracket means attached to said support channel at the opposite side thereof, said glass panel being provided with a glazing channel secured to its support channel engaging edge, said glass panel and bracket being in alignment in a horizontal direction lengthwise of the glass panel with the longitudinal axis of said slot, the width of said slot being greater than the width of said support channel and bracket to provide for insertion of the latter into said window well through said slot, rotatable drive means including a cable receiving drum carried by said bracket, cable means around said drum ex-tending upwardly and downwardly from the drum relative to said support channel, said cable means being respectively secured to the glass panel adjacent the top and bottom parts thereof, said cable means passing within said support channel between the later and said glazing channel, and means operable to rotate said drum in one direction or the other to raise or lower said glass panel.
